CVE-2025-65720Public exploitNetwork attack vector

Host command execution via unauthenticated MCP configuration

Published Jul 15, 2026 · Updated Jul 15, 2026

Command injection in GPT Researcher 3.3.7 through 3.4.4 allows remote attackers to execute host commands through its WebSocket endpoint. The unauthenticated /ws handler passes attacker-controlled MCP command, argument, and environment values to anyio.open_process without validation or an allowlist. Direct exploitation requires network access to the service; a crafted page can reach a normally local instance when a victim opens it.
